The purpose of this paper is to model the manure management policy implemented in the European Union, and more specifically the limit imposed on the spreading of organic nitrogen. A theoretical model is defined in such a way that a number of specificities concerning livestock production can be...

The study proposes a methodology for developing a carbon sequestration baseline attributable to the current use of conservation tillage. An integral component of the methodology is the explicit acknowledgment that there is an uncertainty in the baseline because of the uncertainty associated with...

We build a stylized model to gain insights into the application of conservation payments to protect endangered species in the face of wildlife-livestock disease risks and habitat fragmentation. Greater connectivity of habitat creates an endogenous trade-off. More connectedness ups the chance...

There is considerable interest in watershed-based water quality protection. However, the approach can be highly information intensive, necessitating decisions about the types and amounts of data used to guide decisions. This study examines the Bayesian value of different types and amounts of...

This study investigated the private and social returns to Sustainable Land Management (SLM) practices with an objective of finding practices that reduce the on-farm and off-farm negative effects of land degradation. The results show that SLM practices have robust profits for farmers raising...

Once established, invasive species can rapidly and irreversibly alter ecosystems and degrade the value of ecosystem services. Optimal control of an exotic pest solves for a trajectory of removals that minimizes the present value of removal costs and residual damages from the remaining pest...

Many conservation programs, such as the Conservation Reserve Program (CRP), use indices to select offers. When modeling how changes in the index weights effect program outcomes, one must account for the attributes of available land, and which landowners chose to participate. This paper...

Land-use change is arguably the most pervasive socioeconomic force driving the change and degradation of watershed ecosystems. This paper combines an econometric model of land use choice with three models of watershed health indicators (conventional water pollution, toxic water pollution, and...

This paper examines the impact of dolphin-safe eco-labeling and how it fundamentally altered the spatial distribution of fishing effort and fishermen's willingness to pay to avoid dolphins. To do this, a dynamic discrete choice econometric model is applied to the Eastern Tropical Pacific tuna...
